I'm about to have my 74 Jimmy regeared from 3.07 to 4.10. I read the gear break-in for the gears but I'm sure theyn are talking about rear gears. How should I break in the fronts. Just lock her in and take her for a slow drive down some dirt roads? Is there something special to do for the fronts? Also I'm putting a Detroit Locker in the rear and a Truetrac in the front. I think she will be able to go anywhere I plan to take her. I don't plan to "Hardcore" her but she will be off the beaten path.
